G2 Math HD This is a math game designed for young children. It has count, adding, multiple, minus, speed, distance and many more math calculation options. They are displayed in different railway carriages. Children could click each carriage to learn different math concept or calculations. The app is well-designed in the following aspects: There are also some flaws or controversial points that I found about this app:
 * Vivid colors and fun images;
 * A large number of calculations and math concepts, which gives the users wide range of choices;
 * Interesting animations. The one I clicked was speed. It actually has two cars running from right to left in different speeds and asks the user to choose which color car is faster.
 * User interaction. The users could click or drag to interact with numbers, images, or other options the game provides;
 * Multimedia use. There are images, sound effect, voice of the question, and animation. Several multimedia usage makes the app more fun and attractive to children;
 * Flexible navigation. When playing with one math concept or calculation, the game has a “Home” button inside a balloon so that user could click to go back to home page at any time. This is much better than no way to get back to home page as the first app I reviewed.
 * The design and animations are consistent within the whole game, which can be good and bad. The good thing is the user won’t feel disordered playing the game; the bad side, however, is that people will find it less interesting after playing for a while;
 * When comes to the home page, several trains coming across the screen so fast that it gets blur. Although it stops at last, but when it moves, I cannot look at the screen;
 * Not enough feedback. When users click answers or drag answers around, the app only gives “right” or “wrong” symbols without a simple explanation or hint. I prefer to provide users a little hint when they are wrong and a brief summary when they have the right answer.
